工程建设中重力式挡土墙应用广泛,但存在材料用量较多、体积庞大等缺点,在场地限制等条件约束下宜考虑采用其他挡土墙的结构形式。清远市静福路路侧开挖明渠,因开挖深度较深,明渠距离侧边道路和建筑物较近,经过方案比选,设计采用悬臂式排桩挡土墙外挂网喷混凝土的方案进行支护,取得了较好的实施效果。 Gravity retaining walls are widely used in engineering construction. However, there are some shortcomings such as large amount of materials and bulky materials. The structure of other retaining walls should be considered under the restriction of site constraints. Because of the deep excavation depth, the open channel is close to the side roads and buildings. Through the comparison and selection of projects, the design of the cantilever row piled retaining wall with external net-netting is adopted Support and achieved good results.
